7 Claims. (Cl. 5-347) The present invention relates to mattresses andhas for its main object the provision of Ventilating means whereby themattress, including the felt thereof, may be periodically aerated anddeodorized by means of a suction or blowing engendered by a Vacuummachine.

Another object of the present invention is the provi- "t sion of anopening at the side edge of mattress casing, normally covered by afabric or a perforated flap, and through which opening the nozzle of anair tube connected with a vacuum machine may be inserted after pushingthe ap inwardly of the mattress by the nozzle.

Another object of the present invention is the provision of a suitableframe for engaging the edge of the mattress casing adjacent the openingmade therein, through which frame a nozzle of a vacuum machine may beinserted into the mattress casing for drawing air by suction from themattress casing or blowing air into it in order to aerate, dry anddeodorize the mattress.

A still further object of the present invention is the provision of ascreen fiap hingedly mounted and supported upon the frame aforesaid,with the mechanism for maintaining said ap in a closed relation with theopening bordered by said frame for the purpose of normally maintainingthe said opening closed for thereby preventing any dust or insectsreaching or settling inside of the mattress.

Another object of the present invention is the provision of a perforatedtube suitably supported by one of its ends by the frame aforesaid andhaving its body suitably supported by the mattress springs, so that whensuction or blowing is engendered within said frame the air would bewithdrawn from or supplied to the farthest points removed from saidframe.

With the above general objects in view and others that will appear asthe invention is better understood,

the same consists in the novel construction, combination and arrangementof parts hereinafter more fully described, illustrated in theaccompanying drawing and pointed out in the appended claims.

The mattress with which the present invention is adapted to cooperate isusually made in the form of a rectangular casing which is made of cloth.Usually three cloth layers, namely, inner fabric 16, the middle padding17, and outer prefabricated binding 18, in a superimposed mutualrelation, are used in the manufacture of a mattress, as is shown in Fig.2. For the sake of clarity the mattress casing in other igures is shownas if though made of one sheet of cloth, and will hereinafter bereferred to as mattress casing 18.

Referring to the most simple form of the invention illustrated in Figs.1 and 2, the side of mattress casing 18 is provided with an oblongopening 19, having arcuate ends. In order to stiffen the marginal bodyportion of mattress casing 18 adjacent said opening 19, washer 20,conforming in contour to the contour of said opening i9, is superimposedupon the marginal body portion of casing 18, adjacent said opening.Thereupon an overand-over stitch 21 is made by thread and needle aroundsaid washer 2t) and the marginal body portion of casing 18 covered bysaid washer 20, as is clearly seen in Fig. 2. Thus said stitching 2lwith the body portion of casing 18, adjacent said opening 19, and saidwasher 20, enclosed therewithin, constitute a frame which encloses saidopening i9, and which provides stiifening of the mattress materialadjacent said opening, and of course prevents fraying of the material.

A pair of flaps 22 are provided for interchangeably acting in connectionwith said opening 19 for providing a curtain therefor so as to preventany dust entering the mattress casing through said opening 19. One ofsaid iiaps 22 is sewn by stitches 23 to casing material i8 adjacent onelonger edge of said frame 2l, while the other of said flaps 22 isattached by stitches 24 to said casing material 18, adjacent theopposite longer edge of said frame. When the mattress is laid upon a bedby one of itsrfaces, one of said flaps 22 will cover opening 19, whilethe remaining ap 22 will hang downwardly and out of the path of saidopening 19. When the mattress is turned so as to lie upon a bed by itsopposite face, then said latter flap 22 will drop down in the path ofsaid opening 19, while the first mentioned tiap will hang down and outof the path of said opening i9. By this arrangement one or the otherilap 22 will at all times act as a curtain for said opening 19,regardless as to which face is in contact with the bed springs, as isclearly seen in Fig. 2.

Opening 19 is preferably of a contour corresponding to the contour of anozzle of an air pipe which connects with a vacuum machine, in orderthat when said nozrle is` inserted within said opening i9 itsubstantially fills the Y same. In that manner when either suction orpressure is engendered in a vacuum wmachine no air escapes through theopening and past thesaid nozzle, in order that a full force may act uponthe mattress fabric l5 or all of the multiple ylayers thereof in orderto aerate, dehydrate and deodorize the same in a most etiicient manner.

Referring now to the more advanced form of the present invention,illustrated in Figs. 3 to 8, inclusive, the frame for opening 19 made inthe mattress casing, is preferably made out of sheet metal or plastic.Said frame includes arcuate lip or bead 25, which, in the operativeassociation of the frame with the mattress casing, will contact and bearagainst the outer face of said casing. ln the pre-formed condition or"the frame, the same includes extension 26, which is integrally formedwith said bead 25 on its inner edge. Said extension 26 is provided witha plurality kof slots 27, which deline a plurality of prongs 23. Whensaid bead is superimposed upon the outer face of the edge body portionof mattress casing 1S, adjacent said opening i9, the free ends of saidprongs 2S will be disposed inwardly of the mattress casing. On placingwasher 29 inwardly of the mattress casing, in a contactual relation withthe inner face of the body portion of mattress casing 18, adjacent saidopening 19, said prongs 28 are then bent in a direction away from theinner edge or the frame, until the free ends of said prongs 2S will comein contact with the adjacent edge of washer 29, as best seen in Figs. 6and 7. By virtue of this action and arrangement said prongs 28 willclamp said washer 29 and the adjacent contacting portion of the fabricmaterial 1S, to the free outer edge of said beadV 2S. In this manner theframe is effectively attached to the mattress casing 18, for providing arigid lining for said Vopening 19.

A pair of said prongs 23, adjacent onelonger edge of Vthe frame, arebent intohinge loops 3i), for the purpose hereinafter specilied.

Co-acting with the said frame is flap 31, made. preferably of metal orplastic and provided with a plurality of perforations32, through whichnormally air may pass in or out of the mattress casing, but which arenot largeV ceiving one end of coil spring 36, one set at each end of themattress through the said frame llap 31 will be shifted inwardly uponits hinge against the tension of springs 36. The free edge of said ap311 is inwardly bent for deiining lip 38 so that the same may ride uponthe nozzle without scratching the same when the nozzle is inserted intoor withdrawn from the mattress casing through the said opening.

The adjacent corners of said flap 31 are cut away, as at 39, foraccommodating said springs 36.

A further modification of the present invention, illustrated in 1Figs. 9to 15, inclusive, has a frame which includes bead 40, corresponding inits construction and action to bead l5 in the former modification of theinvention. Said bead 4i) overlies the adjacent body portion of themattress casing 13, and by its outer free edge contacts therewith. Saidbead 4Q at its inner portion is provided with an integrally formed andinwardly extending tubular member 41. Struck out from the body portionof Asaid tubular member 4l, at its portion adjacent said bead 4), is aplurality of lugs 42, which are bent outwardly from the perimeter otsaid tubular member 41, interposed between said bead 4% and said lugs 42is theY adjacent marginal body portion of the mattress casing 18 andwasher 43, wherein the same are maintained in a clamped relation. Bymeans or" this arrangement the frame ismaintained in a rigid positionwith mattress casing 13.

Supported upon the inner end of said tubular member 4l is a metallic orplastic casing made of a pair of complementary sections 44, brought intoa mutual contactual relation along line 45. To maintain the twosections44 in their connected relation a metallic band 46 is provided in anencompassing relation with said sections 44. One end oi said band hasslot 47. The other end is provided with tongue 48, which is passedthrough said slot 4,7, and thereupon bent upon the body portion of theend of said band from which said tongue 4S extends. By virtue of thisarrangement band 46 remains ina firmly tied encompassing relation withsaid sections 44.

Each of said sections 44 adjacent its wall disposed nearest to bead 4i)is provided with recess 49, the two recesses 49 in the two sections 44deline a mouth into which tubular member 41 is passed and in which thesame rests. So as to make a close fit between said tubular member 41 andsaid casing 44-44, said tubular member 41 is provided with acircumferential groove 50 on its outer perimeter, into which grooveadjacent marginal portion of sections 44 along recesses 49, are adaptedto enter. Y

On its longer edge said tubular member 41 is provided with a Vcentralhinge loop 51. Perforated ilap 52 has a pair of loops 53 made upon oneof its longer edges. Loops 51 and 53 receive rod 54. Thus said loops 51and 53, in conjunction with said rod 5 4 constitute a hinge upon whichap` 52 is suspended and upon vwhich the same is adapted for swingingmotion to or away from the adjacent free end of tubular member-41.

Each end of rod 54 has slot 55 for receivingV therewithin one end ofcoil spring Se. The other end of each coil spring 56 bears against theinner face of ap 52, as

, at 57. Coil springs 56 being under tensiomnorrnally plurality ofstruck out and outwardly projecting earsY 58,

each to be engaged by one end of coil spring 59. The opposite ends ofseveral springs 59 are engaged with the adjacent edge wires 60 which aredisposed and supported inwardly of the mattress.

Each of said sections 44, on itsV kface disposed opposite oi is providedwith a complementary extension Y6l, the two extensions,- in theoperative association of the two sections 44, define a sleeve, overwhich pipe 62; preferably made of rubber, is tted. Ringe 63 encompassingthe end ofv-said'pipe 62"'which is over said sleeve,

maintains the adjacent end in a rigid engagement with said sleeve.

The opposite end of said pipe is provided with cap 64. Intermediatelypipe 62 is provided with a plurality of openings 65 through which airmay be sucked from or supplied to the mattress.

Said pipe 62 is supported within the mattress by a plurality offasteners 66, provided with central loops 67 within which pipe 62 rests.Each end of each fastener 66 is provided with hook 68 for engaging coils69 of the inner mattress springs.

From the hereinabove description it will be readily apparent that theframe and the tubular member 41 are supported within the opening of thefabric material 18 of the mattress. Springs 59 further support saidtubular member 42 against lateral movement. Casing 44 is supported bymeans of tubular member 4i as weil as by pipe 62, the latter beingsupported by a plurality of fasteners 66.

It will be readily seen that pipe 62 may be as long as desired and mayreach as far within the mattress as is desired.

It is also noted that flap 52 remains within the casing deiined bysections 44, and a nozzle of an air pipe connecting with a vacuummachine, when inserted through tubular member 4i, on pushing ilap S2inwardly of the said casing, enters said casing dened by sections 44.

V-fhile there is described herein preferred embodiment of the presentinvention, it is nevertheless to be understood that minor changes may bemade therein without departing from the spirit and scope of theinvention as claimed.
